Android Question Scan information from Camera

Keith Yong · Jan 30, 2020

Hi, I would like to achieve to use camera to scan a card in order to retrieve the result input by player. As you can see the card that I attach, the player will highlight the number on the card for each round. Appreciate if you can advice me how can I achieve this. Thanks

You need to get the photo (using a Camera library) and an OCR library.

I fear that even an excellent OCR will have difficulty recognizing texts both horizontally and vertically, with a single scan.

This is an old thread:

You can search the site for newest libraries.

This seem like will read the entire text in the card, but I only need to read the number which is highlighted and get the round number which display in the first row. Is there anyway work like OMR concept?

You have to try, if the card is large enough you should have no problems.
